Description

Safety loading device for fuse using worm gear and motor {SAFETY ARMING DEVICE FOR FUSE USING WORM GEAR AND MOTOR}

The present invention relates to a safety loading device for a fuse using a worm gear and a motor.

In general, a fuse coupled to an ammunition such as an aerial explosive projectile is provided with a safety loading device to prevent loading within a predetermined time before launch or after launch.

The safety loading device prevents safety accidents such as an explosion in the handling process or a close distance after firing by preventing the ammunition from being loaded before a certain amount of time has elapsed before and after firing.

A conventional safety loading device is a mechanism in which a slider is moved or a rotor is rotated to be loaded by a separate external force such as an inertial force or a spring, and includes a separate position fixing device to maintain a safe state or a loaded state.

Existing fuse safety loading devices employ a method of directly assembling and rotating a rotor to a gear motor to increase a gear reduction ratio of the gear motor to prevent the rotor from rotating in a high impact environment.

However, the conventional safety device for the fuse has a problem in that the use of the internal space of the fuse is reduced and the overall shape of the fuse is increased by directly assembling and rotating the rotor to the gear motor.

In detail, in order to increase the gear reduction ratio of the gear motor, it is inevitably necessary to add a gear, which makes the gear motor longer, invades the space of the electronic part of the fuse, makes the shape of the board strange, increases the number of boards, increases the overall size of the fuse, and increases the size of the electronic part. It also caused various problems, such as a low degree of integration.

In addition, the conventional safety device for the fuse adopts a structure using a contact point, a contact board, and electrical wiring to maintain the safety and loading state of the explosion series, which has the disadvantage of being weak against external shock and vibration.

Meanwhile, FIG. 4 is a view showing an embodiment of a worm gear box of a safety loading device for a fuse using a worm gear and a motor according to the present invention, and FIG. 5 is an enlarged view of part A of FIG. 4 .

6 is an exploded perspective view showing an embodiment of a worm gear shaft in an embodiment of a worm gear box of a safety loading device for a fuse using a worm gear and a motor according to the present invention.

4 to 6, in the fuse safety loading device using a worm gear and a motor according to the present invention, the worm gear box body 200 is rotatably positioned inside the gear box housing 230 and the gear box housing 230 It includes a worm gear 210 and a worm wheel 220 that rotates in engagement with the worm gear 210.

In addition, the motor shaft 310 of the rotary motor 300 passes through the side of the gearbox housing 230 and is located in the gearbox housing 230, and the worm gear 210 is a motor located in the gearbox housing 230 It is mounted on the shaft 310 and rotates integrally with the motor shaft 310.

In addition, the worm wheel 220 is rotatably positioned in the gearbox housing 230 and rotates in engagement with the worm gear 210, and the wheel gear shaft 221 penetrates the gearbox housing 230 and is rotatably positioned, It is positioned so that the end side protrudes outward of the gear box housing and becomes the output shaft of the worm gear box body 200.

The rotor member 100 is mounted on the output shaft of the worm gear box body 200, that is, the wheel gear shaft 221 of the worm wheel 220, and is integrally rotated together with the worm wheel 220.

The worm gear 210 is positioned to be movable in the longitudinal direction of the motor shaft 310, and elastic supports 500 for elastically supporting both ends of the worm gear 210 are positioned inside the worm gear box body 200.

The elastic support part 500 supports both end sides of the worm gear 210 movably positioned in the longitudinal direction of the motor shaft 310 so that the worm gear 210 can be stably engaged with the worm wheel 220.

In the worm gear 210, a shaft through-hole 211 through which the motor shaft 310 passes is positioned, and a shaft engaging groove 212 is positioned on an inner circumferential surface of the shaft through-hole 211.

In addition, the motor shaft 310 has a shaft protrusion 311 inserted into the shaft locking groove 212 on the outer circumferential surface in the longitudinal direction, and the shaft protrusion 311 is formed at least as much as the movement range of the worm gear 210 to form a worm gear ( 210) to be moved stably in a straight line.

A plurality of protrusions 311 protrude from the outer circumferential surface of the motor shaft 310 to stably transmit the rotational force of the rotational motor 300 to the worm gear 210, and to disperse and support impacts generated from the outside to improve durability due to impacts. can be secured

The worm gear 210 is elastically supported by the elastic support part 500 so that when the stopper protrusion 120 is caught on the stopper engaging part 130 and the rotation of the rotor member 100 is stopped, the restraining force due to gear engagement is lowered.

When the rotor member 100 is switched from the non-loading position to the loading position by using the worm gear 210 and the worm wheel 220, the stopper protrusion 120 is caught by the loading stopper engaging part 132, and in the non-loading position When returning to the loading position, the stopper protrusion 120 is caught by the loading stopper engaging portion 131 .

When the stopper protrusion 120 is caught in the loading stopper engaging portion 132 or the loading stopper engaging portion 131 and the rotation of the rotor member 100 is restricted, the rotational motor 300 stops operating while rotating the motor The load applied to the 300 increases, and the current value applied to the rotation motor 300 suddenly increases, and a strong restraining force is generated in the gear meshing of the worm gear 210 and the worm wheel 220, which is the characteristic of the worm gear 210 am.

Due to the characteristics of the worm gear 210, the rotation of the rotation motor 300 is limited by the stopper structure, and the current value applied to the rotation motor 300 suddenly increases, and the gear meshing of the worm gear 210 and the worm wheel 220 is strong binding force arises.

The worm gear 210 has a degree of freedom to be movable in the longitudinal direction of the motor shaft 310 and is elastically supported by the elastic support 500 so that when the rotation of the rotational motor 300 is limited by the stopper structure, the worm wheel 220 and The occurrence of a strong restraining force due to gear engagement is prevented, and the load applied to the rotary motor 300 is gradually increased so that the current value applied to the rotary motor 300 is gradually increased.

As an example, the elastic body 530 is a coil spring, and the second surface of the elastic supporting member 510, that is, the elastic body support surface supporting the elastic body 530, has a ring-shaped spring support portion 511 supporting the position of the coil spring. ) is positioned so that it protrudes.

The spring support 511 protrudes in a ring shape to support the position of the coil spring so that the coil spring can be stably compressed and restored.

The rotation guide ball body 520 allows the worm gear 210 to rotate smoothly while being elastically supported by the elastic support part 500 .

The worm gear 210 can smoothly rotate while being elastically supported by the elastic body 530, and minimizes the load applied to the rotary motor 300 by minimizing friction with the elastic support 500 during rotation.

In addition, although the safety loading device for fuses using a worm gear and a motor according to the present invention is not shown, when the current applied to the rotary motor 300 is greater than a preset current value, a current blocking unit for blocking the current applied to the rotary motor 300 (not shown) is further included.

The current blocking unit may be variously modified and implemented using a known current blocking circuit structure, and a detailed description thereof will be omitted.

The current blocking unit cuts off the current applied to the rotation motor 300 when the current applied to the rotation motor 300 is greater than the predetermined current value, so that the worm gear 210 and the worm wheel 220 are engaged to recover to a strong binding force, that is, normal voltage The operation of the rotary motor 300 is stopped before an impossible gear engagement occurs.

The operation of the safety loading device is being checked before the fuse 10 is mounted on the bullet, and while the operation of the safety loading device is being checked, the rotation of the rotor member 100 is restricted and the current value of the rotary motor 300 rapidly increases. In this case, a problem arises in which it is impossible to return to normal voltage due to the strong binding force of the worm gear 210 and the worm wheel 220.

In the safety loading device for a fuse using a worm gear and a motor according to the present invention, the worm gear 210 is movable in the longitudinal direction of the motor shaft 310 and is elastically supported by the elastic support part 500, so that the rotor member 100 moves to the loading position When the rotation is restricted by the stopper structure at the non-loading position, a strong restraining force is prevented from occurring in the gear meshing of the worm gear 210 and the worm wheel 220, and the current value applied to the rotary motor 300 suddenly increases prevent becoming

In addition, in the fuse safety loading device using a worm gear and a motor according to the present invention, as the current applied to the rotation motor 300 gradually increases by the longitudinal movement structure of the worm gear 210, the rotation motor 300 as a current cut-off unit If the current applied to the current is greater than the preset current value, the current applied to the rotation motor 300 can be cut off, so that the worm gear 210 and the worm wheel 220 are meshed to form a strong restraining force, that is, before gear meshing that cannot be restored to normal voltage occurs The operation of the rotary motor 300 is stopped.

That is, in the fuse safety loading device using the worm gear 210 and the motor according to the present invention, when the rotor member 100 rotates to the loading position and the non-loading position during inspection, the rotation is restricted by the stopper structure, and the worm gear 210 It is possible to prevent a strong restraining force from being generated in the gear meshing of the worm wheel 220 and the occurrence of defects due to the strong restraining force due to the gear meshing of the worm gear 210 and the worm wheel 220 during inspection, and operation during actual operation stability can be ensured.
